Transformation toughening occurs when a material undergoes worry-induced stage transformation. Some ceramics are effective at undergoing stress-induced martensitic transformation, which consists of an energy barrier that has to be overcome by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the transition between an "austenite" or... https://deanuvvsq.jts-blog.com/37926534/what-does-aluminum-nitride-pcb-mean
